What is “__name__” and “__main__” in Python? A guide to unravel the mystery behind the Python code of __name__ and __main__
What does this line of code mean?
if name == “main”:
The whole idea behind this line of code is that when you are importing from a module, you would like to know whether a module’s function is being used as an import or if you are using the original “.py” file of that module. In such cases, we use the above line.
When your script is run by passing it as a command to the Python interpreter:
all of the code that is at indentation level 0 gets executed. Functions and classes that are defined are defined but none of their code gets ran. Unlike other languages, there’s no main() function that gets run automatically- the main() function is implicitly all the code at the top level.
A guide to knowing how to use PyPi for installing modules and packages and also create your own ones. PyPi is a repository for open-source third-party Python packages. We automatically install pip too. pip is a simple way to download packages at the command line directly from the PyPi repository.
When your Python code grows in size, most probably it becomes unorganised over time. Keeping your code in the same file as it grows makes your code difficult to maintain. At this point, Python modules and packages help you to organize and group your content by using files and folders.

This article will explore how to generate QR code in Python and some useful creation features from pyqrcode library. QR codes recently became more popular than ever before, yet few people know that the first iterations of QR codes were created back in 1990s in Japan for the automotive industry.
